Abstract

Described is system and method for RFID tag communication including transmitting a command signal in a time slot to a plurality of wireless communication devices, the command signal indicating initiation of an identification process for identifying each of the wireless devices, the identification process including a plurality of time slots and computing a probability that a subsequent command signal transmitted in a subsequent time slot will cause only one of the wireless devices to transmit a response signal in the subsequent time slot.
